Application filed May 23, 19155. Serial No. 99.3%.

To all 1.01 207% it may; concern lie it known that l, l iroims citizen of the United States, residing; at Bclhaven, in the county of ,aufort and State of North Carolina, have invented new and useful Improvements in l ce Crezun Freezers. of which the following is a speciiication.

This in vcntion plates to improve-nientsin refrigerating apparatus and has particular application to apparatus for use in the 1nan ul acture of ice cream and the like.

In carrying out the present invention, it is my purpose to provide refrigerating apparatus for the manufacture of ice cream and. the like wherein the receptacle that contains the n'iaterial to be congealed. Will be held in the freezing tank in such manner as to prevent floating of such receptacle when the .material is removed therefrom and wherein the material in the receptacle may he maintained in a congealed state by ice containers surrounding the receptacle and submerged in brine.

lVith the above and other objects in View the invention consists in the construction, combination and arrangement of parts hereinafter set forth and falling within the scope of the claim.

In the ai'rcornpanving drawing;

Figure l is adiagrennnatic sectional View through freez ng apparatus constructed in accordance with the present invention.

Fig. 3 is a perspective view oi" one of the ice containers.

Fig. 1 is a, top plan view showing a modilied form of ice container.

Fig. 5 is a detail View showing the means for holding the receptacle in the freezing tank.

Referring now to the drawing in oletztil 1 designates a freezing tank which is preferably. although not necessarily, rectangular in horizontal section. This tank 1 is provided with a removable cover 2 and orrsn centrally of the mm at the upper e d thereof is an annular band 3 provided with radial arms 1 L GIBBS, a.

terminally connected the side Walls of the freezin 1 Where hv the band 3 will be held in proper position in the tank 1. 5 designates receptacle adapted to contain the material to he congealed. This receptacle is designed to he placed in the tank 1 and is formed, adjacent to its upper end. with outwardly projecting diametrically opposed pins 6 engagesble in. bayonet slots 7 formed in the hand 3, toe pins and lun/onct slots acting to hold the receptacle in proper position in the tank 1. ll ithin the tank 1 around the receptacle 5 are ice containers 8 Whose outer Walls are parallel with the inner aces off the respec tive Walls of the freezing tank, and Whose sides are mitered or beveled to lit-one another, and Whose inner Wall, are rounded to conform to the shape of the receptacle 5 clearly illustrated in Fig. 2 of the drawing. Each ice container 8 is provided with removable top 9 and journaled in the top 9 is R stem 10 having the inner end formed with a. locking lug 11 and the ou'ar end equipped with a. handle 12. The h 11 is adapted to hold the cover in closed position.

13 designates a. brine tank arranged along;- sicle of the freezing tank 1, and leading from. the lower end of the brine tank 13 to the lower end oi the freezing tank a pi e 1 1 provided with a hand operated cut on valve Leading into the upper curl of the tank 13 is a. supply pipe 16 coi'inectee with a brine supply tank 17. At tl'ic end of the pipe 16 in the tank 13 is a cut oil val 18 connected to a float 19 arranged Within. the tank The brine flows from the supply tztnlr 17 into the tank 13 and then through the pipe 14- into the freezing tank around the ice containers and the rceeptach; 5 and the level of the brine in the tank 15: rises the liout elevated to cut oil the valve 18 and the tanks 13 and 1. ar ranged side by side the level of the oi-inc in the irreezi g tank corresponds to the level of 20 designates an the brine in the tank 13. overl'lo'iv pipe connected to the freezing tanl 1 and leading to a suitable Waste receiver.

When it is desired to remove the ice contuiners 8 from the freezing tank the cut valve 15 is usually closed to cut oli' cornmnnicrtlion between the freezing tank and the tank 13 so that the freezing tank will not flooded incident to the displactmmnt of the brine when the ice container is replaced in the freezing rank. However, desired to temporarily witl'itlrew an ice container, as for replenishing the ice therein. it

can he done Without necessurilv cutting ell the flow by means of the valve 15, because the hrinc will not rise r'picll v Within the freezing); tank the al' sehce of the recepiw clc. tlfhcn latter is reinserted, it will 01? if it should be course raise the level of the brine within the tank 1, but the overflow. 20 takes care of the excess of brine so that no salt water runs over into the cream receptacle 5.

When two receptacles 5 are inserted in the freezin tank a central ice container 21, shown in Fig. 4:, may be placed between the receptacles and the opposite sides of the container 21 are rounded to conform to the curvature of the receptacles. It will be observed that all ice containers 8 and 21 are so shaped that their inner walls conform with the curvature of the cream receptacle 5,

Whereas their edges are beveled to conform with the shape of the edges of the next adjacent containers and yet to permit them to' be raised from or replaced within the main tank 1. In such removal and reinsertion, each ice containr must of necessity pass the radial arms 4, a d in order that it may do so freely there is lefta certain space between the contiguous beveled edges orsides of the containers, orsin other words they are not distinctly in contact with each other.

This space, together with that outside and 25 inside the containers, afiords room for the brine to flow all around the ice containers and all around the cream receptacle.

I claim:' a

The herein described ice cream freezing apparatus comprising an upright freezing tank, an upright cream receptacle centrally disposed therein, a band to which the upper end of the receptacle is detachably connected and through which it may be removed, radial arms from the band to the walls of said tank, and a seriesof ice containers surrounding said receptacle, each having its outer wall paralleling the wall of the tank, its inner wall conforming to the adjacent wall of the receptacle, and its sides beveled to parallel the sides of the contiguous containers and spaced therefrom whereby the containers may be raised past said radial arms.

In testimony whereof I affix my signature.
